FILTER.

SPECIFICATION forming part of Letters Patent N0.,490,520, dated January24, 1893.

Application filed April 4, 1892. Serial No. 427,662. (No model.) u

To all whom it may concern:

Be it known that I, AUGUST WERNER, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Filter, of whichthe following is a full, clear, and exact description.

The object of the invention is to provide a new and improved lter, whichis simple and durable in construction, very effective in operation andarranged to thoroughly and quickly filter beer, wines, liquors and otherliquids.

The invention consists of certain parts and details and combinations ofthe same, as willA be hereinafter described and then pointed out in theclaim.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line1-1 of Fig. 2; Fig. 2 is a transverse section of the same on the line2-2 of Fig. l; Fig. 3 is an end view of the series of connected frames;and Fig. 4 is a side elevation of a modified form of the improvement.

The improved filter, is used in a filtering process described in ymyapplication, Serial No. 431,676, filed by me May 3, 1892.

The improved filter is providedwith a receiving vessel A, of suitablesize and dimen.

sions, and connected at its top with a supply pipe B leading to thestorage cask D containing the liquid to be filtered. The pipe B is alsoconnected with a tube C in which any bubbles carried by the liquid fromthe storage cask D to the vessel A can rise and dissolve, as is morefully described in the application above referred to. Part of the tube Cmay be made of glass so as to enable the operator to inspect thecondition of the liquid rising in the tube.

On the bottom of the receiving vessel A is arranged an outlet valve E,for discharging sediment collecting in the vesselA or emptying thelatter whenever desired.

Within the vessel A is suspended the lter proper F, provided with aseries of connected frames F, F2, F3, each of which is provided with aseries of transversely extending plates G, formed with perforations, thesaid plates being preferably of the same width as the respective frameF', F2, or F3. Each of the frames is inclosed Within a cover I-Lmade ofcanvas, wire netting or other suitable fabric, the said cover restingagainst the 4outer edges of the transverse plates G, on both sides ofthe frame and also is supported on the outer Aor inner surface of theframe. The top bar of the middle frame F2 is provided with an outletpipe I passing through and attached to the top of the receiving vesselA, the outer end of the said pipe being connected with' the outlet Jleading to the receptacle or other vessel to be filled with the filteredliquid. l

Between the filtering fabric of two adjacent frames is packed a looseiiltering material K, made of paper, wood pulp, or other suitablematerial. On the outer sides of the two outermost covered frames F andF3 are placed the longitudinally extending bars L arranged in sets oftwo bars connected with each other by bolts N. By screwing up the nutson the latter the several frames with the filtering material Kv betweencovers of adjacent frames are securely locked in place and ready to besuspended in the casing, as above described. The outer sides of theoutermost frames F and F2 are preferably covered with an additionalcover O of coarse canvas, wire netting or like perforated article toprotect the respective cover H made of finer material. The ends of thisadditional cover are tacked or otherwise secured to the respective frameprevious to assembling the several frames and locking the same inposition by the bars L and bolts N, as above described.

It will be seen lby reference to the drawings that a suflicient space isformed between the lilter proper F and the inner walls of the receivingVessel A, so that the liquid entering the said vessel A through thesupply pipe B can pass around the entire filter F and nally IOO blesarising in the valve can pass into its pipe and dissolve therein at thelevel of liquid, which level is the same as that of the liquid in thecask D.

It will be seen that each filtering cover H is evenly supported on bothsides of the frame by the edges of transverse plates G, so that theliquid can be forced with considerable pressure through the saidfiltering material Without spoiling or breaking the same. The outermostsides of the covers of the frames F and F3 are additionally protected bythe coarse covers O.

As shown in Fig. 4 a series of lters F may be connected by their outletpipes I with a horizontal pipe J connected with the discharge pipe J;the several iilters thus connected being arranged for suspension in asingle casing A. The 'ilter proper F can be conveniently taken apart byunscrewing the bolts N to permit cleaningr the individual frames F', F2,F3, and the filtering material K.

A filter constructed in this manner is very effective in operation asthe liquid is thoroughly filtered and finally passes into the out- Y letpipe I in a pure state.

It is understood that I do not limit myself to the number of frames inthe iilter F shown, as anydesired number of frames maybe united in themanner described to form the filter proper.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent:-

A filter comprising a receiving vessel connected with the supply, aseries of connected frames suspended in the said vessel and of which oneis connected with the outlet, each frame being provided with perforatedtransverse plates, a cover made of iilt'ering fabric and inclosing eachof the said frames and stretched over the outer edges of the saidplates, alayer of loose lterin g material placed between the covers oftwo adjacent frames, and means, substantially as described, for con-'necting the several frames with each other and to hold the loosefiltering material clamped by said means between said frames,substanltially as shown and described.
